-- @testpoint: opengauss关键字only(非保留)，作为函数名,部分测试点合理报错

--关键字不带引号-合理报错
drop function if exists only;
create function only(i integer)
returns integer
as $$
begin
    return i+1;
end;
$$ language plpgsql;
/
--关键字带双引号-成功
drop function if exists "only";
create function "only"(i integer)
returns integer
as $$
begin
    return i+1;
end;
$$ language plpgsql;
/
--关键字带单引号-合理报错
drop function if exists 'only';
create function 'only'(i integer)
returns integer
as $$
begin
    return i+1;
end;
$$ language plpgsql;

--关键字带反引号-合理报错
drop function if exists `only`;
create function `only`(i integer)
returns integer

--清理环境
drop function if exists "only"(integer);
